especially for manicuring, and more par# ticularly to a buffer havmg a reversible bufiing block and a detachable handle adapted to be applied to the block `with either buiiing surface of the block in position for- USB.

proved buifer of this kind, and especially to provide a .reversible buffer of simple con-V struction so constructed that the handle may be readily and quickly applied to and removed from the buling block to reverse the position of the block with res ect? to thev handle so as to bring either bu ng surface thereof into position for use.

To these ends, the invention consists in the features of construction and arrangement of parts as hereinafter described and' specifically pointed out in the claims.

The accompanying drawings illustrate a typical embodiment of the invention..

In said drawings Figure 1 is a perspective view of a buffer showing a builing blockv 4 is a sectional view of the block taken onv line 4--4 of Fig. 2 and showing a portion of the handle in position as it is about to be applied to the block;l Fig. 5 is a transverse sectional view of the body of the block without the buiiing material; and. Fig. 6 is'a similar view but showing the ,complete block' provided with its builing surfaces.

Referring to the drawings, .the buffer" block 1 which maybey of any desired size andy made of any I`desired material, preferably of w'eo'd,`i`s`"of the'usualelongated form having its sides tapered yoff toward each end. The particular form of block may, of course, be varied. Opposite faces 2 and 3 of the body of the block which are to receive the bu-iiing material are desirably made slightly longitudinally concave as shown, thus providing a block which is thicker transversely to its faces 2 and 3 at the ends Specification of Letters Patent.

than it is in itsmi'ddle portion. The sides of the block are formed with a slot or channel 4 extending-around the -block adjacent each ofthe faces 2 and 3 for receiving, as shown in Fig. 6, the edge portion of a piece of chamois or kid or similar vmaterial 6 which extends over the face of the block to provide a bulhng surface, a suitable mass of a soft substance 5 being provided as a ll'ing beneath the lmaterial 6. The dimensions of the slots or channels 4 are determined by the nature of the material 6. rlhe edges of the pieces of material forming the buiin'g surface may be held securely in the slots 4 bysuitably filling means such as a piece of braided or twisted silk 7 the thickness of which is sufficient when forced into the slot along with the edge portion of .the bufing material to securely hold the same.y a f .For engagement withthe handle, the sides ofthe block vbetween the channels 4 are curved ,inwardly or hollowed ,out to provide a guiding Aand positioning groove `8 with outwardly flaring walls, such groove extending most desirably. completely around the block and the Width and depth of the guiding groove being greatest atthe ends of the block as shown at 10 and decreasing to- Ward the center block.

The handle 15 comprises a hand. gri 16 and block engaging portions extending om the hand grip and adapted to hold the block by engagement in the groove 8. A suitable form of handle is shown in the drawings and is more specically described fand claimedin my U. S. Patent No. 1,014,629, dated January 9, 1912. In this handlethe block engaging portions. or parts carried by the handgrip 16 are formed of wire bent 'to provide a closed U-shaped end member 17 adapted to seat in the portions of the groovev block has 'been positioned in the handlea4 As shown, the ends of the separablemembers 18 carry knobs 19 which are adapted to' snap by eachother and to interlock one f with the other. The engaging portions 17'- and 18 lof the handle are connected with the hand grip by upwardly and then inwardly extending portions of the wire as or middle portion of the 'shown and as more fullydescribed in my said patent.

The block is positioned in the handle and removed therefrom by relative endwise movement between the block and the handle, the ends of the separable members 18 of the handle running in the groove 8 of the block during such relative movement. To remove the block from the handle, 4it is only necessary to release the interlocking ends of the separable memberslS of the handle and then withdraw the block, as by grasping it with the fingers on its opposite bufiing faces. To

reconnect the handle and block with either buing surface of the block outermost, the block and handle are brought together with one end of the block entered between thev ends of the separable engaging members of the handle and then by relative endwise movement they are positioned as' shown in Fig. 1,:-whenbyturning the interlocking knobs ofthe handle past each. other the handle may be securely locked tofthe block and the two members will then`v necessity of any considerable degree of care in entering the end of the buiiingjblock be- A tween the ends of the separablehandle meinbers and in sliding the parts into relative' position is entirely avoided. Thewide'laring the entering ends of the handle members as the block and handle are brought together, and also insure the proper engaging' position of the engaging members of the handle at both. ends of the block when the handle and block are brought to operative position and the separable han' dle ymembers locked together about theiend of the block. It will be observed that the functions of the -wide flaring walls of-the e guiding groove are performed moreparticularly in the portions of thegroove adjacent the ends' of the block, and that the narrowv ingof-the groove towardthe middle of the bljockdoes not, therefore, interfere with the securing of the desiredresult; and this narrewing 'ofthe groove in 'of the .block is of advantage especfaillyy in block to be made of s .ji'ininiandain securing t e groove at the ends lof the block without un.- duly inc easingn the thickness-of the block kas a whoe.- l

' What lis claimed is:

. 1'. ihbuffer comprising vin' combination a reversible buffng block havingA buliing surfaces on opposite faces thereof, and a dee beiv held ,against relative separating movement,

walls of tli'e groove at the ends ofthev block act to position the block with either with outwardly the central portion ing the engaging tachable handle, the handle having a hand grip and block engaging portions extending from the hand grip and including separable members for engaging one end of the block, and the block having its surface between its buii'ng faces formed'to provide a guiding and positioning groove with outwardly flaring walls adapted to receive the block engaging portions of the handle, said groove being of a width substantially? greater than required for holding the engaging portions of the handle in positioniwhen seated therein, whereby the handle maybe readily applied to' or removed from the block with either buiing surface yof the block outermost by a relative endwise movement of the block and handle with the engaging portions of the handle running in the block groove.

2'. A buffer'comprising in combination a reversible buiing block having bufiing 'surfaces on opposite faces thereof, and a detachable handle, the handle having a hand grip' and block engaging portions extending from the hand grip. and including separable members for 'engaging one end of the block tween its buiing faces formed to provide a guiding and positioning wardly Haring' .walls adapted to receive the block engaging portions of the handle, said groove at and near the ends of the block being of a width substantially greater than required for holding the engaging portions of the handle in position when seated therein and decreasing in width toward the middle portion of the block, whereby the handle maybe readily applied to or removed from buffing surface of the block outermost by a relative endwise movement of the block and handle with the engaging portions of the-handle running in the block groove. .3. A reversible buiiing block having opposite faces provided with builng material, and having its surface all the way aboutl the block between the bufling faces formed to Drovidea guiding and positioning groove flaring walls adapted to receivethe block engaging portions of a detachable handle, said groove being of a width -substantially greater'than required for holdportions of the handle in position when seated therein.

In testimonywhereof I have signed my name to this specification in the presence of two subscribing witnesses.
